To all whom-it may concern:

Be it'lmown thatI, Hnnnr Wm DAR Chicago, in the county of Cook and State of Illinois, "have invented certain new and useful Improvements in Cyhnder Washmg- 1 Machines, of which the following is a specification- My invention relates in generalto washing machines, and more particularly tothe ty known as cylinder-washing machines.

y invention has for its objects to pro' duce a washing machine which will be thor- 'oughly sanitary, and to fully accomplish this the machine is preferably made entirely ofmetal, the use of wood being eiiminated; to provide a supporting frame which will be strong and rigid, and at the same time of simple construction; to so design certain members of the supporting frame that they will afford means for securely supporting a motor and driving mechanism, as well as contribute to the strength of the machine;

to provide facilities for easily introducing and removing the articles; to so construct the machine that the articles will be thor- .oughly cleansed without injury; and to provide for the substantial support of a clothes. wringer in convenient position to receive the articles as they are removed from the cylinder.

My invention has for its general object the production of a washing machine which will simple in construction, inexpensive in manufacture, efiicient in operation and durable in use.

' atop plan view, the cover being removed My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated and embodied in av convenient andpractical form, and in which Figure 1 isa vertical section of the machine, taken on the line 1 in Fig. 3, looking in the direction of the arrow,'and further shows the position assumed by the drum relative to the casing in dotted lines. Fig. 1 is a detail horizontal section taken on the line 1' in Fig. 1 looking in the direction of'the arrow. Fig. 2 is a vertical section of the machine, taken on the line 2 in Fig. 3, look-' ing in'the direction of the arrow. Fig. 3 is and certain other parts being broken away.

Figs. 4, 5 and Gare perspective views in deof the corner pieces, and F ig.- .9 is-a section on the line 9 of Fig. 1, looking in the direction of the arrow.

vention which I have chosen to illustrate in the p y g drawings,

the machine as eachcorner-post consisting of an upper secjtion l5.an d a lower section 16 joined tolower section 16 and lies within the angle of the. upper, section v 15. Detachable casters are provided for the lower ends of the corner posts, each casterconsisting of a bracket clamped in place by means of the ring 21. Two corner posts 15 at one end of themachine are joined; together by the horizontal transverse brace 22-23, this brace having an angular cross section with one flange 22 in a vertical planeand the otherflange 23 in a horizontal plane. The motor .24 is' .at-

of these bars are bent atright angles around the corners of the machine, as indicated by the reference numeral 29. The. corner posts 15 are'made with grooves to accommodate these ends 29.

26, are two small inside corner angle pieces 30. The right hand ends of the stiflened these bein shaped to accommodate them, as indicated %y the reference numeralBl. At the front of the machine, fitting the inside corners thereof, are the two corner braces 32, as shown in Figs. 1, 2 7 and 8. Each of these corner braces consistsof a main flange tail of cross braces ofthe structure. Fig. 7.;

1s a horizontal section on the Iine T'ofFigLJ .2, looking inthe direction of .thQlH'IOW- Fig. 8 1s a perspectlve-view in detail of one In the particular embodiment of my in-' a whole is supported upon four corner posts,

20 carrying the caster wheel 19 and being.

tached to the under side of the horizontal, flange 23. The horizontal brace 2223 is 7 attached to the corner posts 15 by means of spectively on thefront and back sides of seen in Figs. 1, 2 and 7. The left-hand ends 'members 28 stick under the corner posts 15,-

gether" by bolts 18 which pass through a tongue 17 that projects upward from the parallel therewith is another brace 26 contac'hed to them bymeans oft-he bolts 27. Y

At the two corners of the machine at the rear thereof, at the same height as the brace L 32which fits against the side wall of the washing machine tank and a flange 33 at a right angle thereto which fits against the 'its ends 38 projecting under the edges of corner posts 15 which are shaped to accom modate them.

The washing machine tank consists of a curved piece of sheetmetal 39 having its front and rear ends respectively 40 and 41 bent up in parallel vertical planes. Attached to this curved sheet are the side sheets 42 and 43.

I will now proceed to describe the frame work about the top edge of the washing ma- Chi [119.2

At the front there is an inside edge plate 44 having a lip or flange 45 which rests upon the top edge of the sheet metal wall 40. This brace 4445 extends the full inside width of thetank, its ends abutting against the respective side walls 42 and 43. Across the top edges of the sides 42 and 43 on the inner faces thereof are the two braces 46 and 47 and having their respective top flanges 48 and 49 extending above the top edges of the side walls. The upper edges of the corner braces 32 (Fig. 8) are drawn out to a thin edge, as indicated by the reference numeral 50, and this thin edge is slipped up under the ends of the front top brace 44-45 and the two side top braces 46 and 47. The portions of the front top brace 44-45 under which these corner braces 32 are introduced are indicated by the reference numeral 51. Across the inside top rear edge of the washing machine tank extends the plate 52 having a lower flange 53 and an upper flange 54, as shown in Figs. 1, 2 and 5. In the same position but just outside of the tank wall 41 is the plate 55, the two plates 52 and 55 being clamped together by means of screws 56.

On the rear left corner of the machine overlying the corner post 15 is the angular member 57 which is extended upward in a bracket 58-59 that carries a journal bearing for the shaft 60. This shaft 60 transmits power from the motor 24 through connections not shown in the drawings to the Wringer 61. This wringer 61 has clnmping jaws 62 and 63 which carry thumb screws 64 adapted to engage the rear top edge plates 52 and 55.

The right-hand side wall of the machine has a casting 65 attached to the inner side thereof. This casting is shown in dotted lines in Fig. 2 and it has a flange 66 which is formed as shown to make a socket for the trunnion 67. This casting is attached. to the side wall 42 by means of screws 68.

Attached to the inside of the left-hand side wall 43 is the extended plate 69, the upper end of which projects under the offset portion 71 of the top edge brace 46. The front ed e of this casting is thickened as indicated y the reference numeral 69 and carries a flange 70' which isshaped to form a socket for the trunnion 71. The rear end of the plate 69 is indicated by the reference numeral 72 and itabuts against the rear wall 41 of the washing machine tank, being secured to the corner post 15 and the overlying corner brace 57 by means of, stud bolts 73. The gear wheel. 74 is mounted on a shaft which projects through the left-hand side wall 43 of the washing machine tank. There are driving connections from the motor 24 to the rotating gear Wheel 74, but these are not shown in the drawings. A plate 75 is .pivotally mounted upon the shaft of the gear wheel 74, but its oscillatory movement about said shaft is limited by the pin 77 engaging the slot 76. A projecting lip 78 from the plate 69 overhangs the oscillatory plate 75. The idler wheel 79 in engagement with the gear wheel 74 is mounted on the oscillatory plate 75 and communicates rotation from the gear wheel 74 to another gear wheel 80 on the same plate 7 5. The teeth of this gear wheel 80 are in engagement with the circumferential series of studs 81 on the end of the drum 94. These studs 81 are carried by a spider 82, which also carries the trunnion 71. It will be seen that the washing drum 94 is supported by the two trunnions 67 and 71. The rod 83 has one end pivotally connected to the oscillatory plate 75, the other end of the rod 83 passing through holes 84 in the flange 70' just above the trunnion 71'.

The side top braces 46 and 47 have inside flanges 85 which are adapted to support These flanges the washing machine cover. are interrupted at an intermediate point of each, as indicated by the reference numeral 86, these gaps being intended to afford a.

passage for the trunnions 67 and 71 Whenever it may be desired to lift the washing drum 94 in or out with respect to the washing machine tank. At the front ends of the flanges 85 are the studs 87, and extending downward from these studs 87 are short flanges 88 which formconfirmations of the lips or flanges 34 of the corner braces 32. The cover 89 is shown in closed position in Fig. 2 andin open position in Fig. 1. Its front and rear edges are rolled over, as indicated at 90, and on its side edges are the folded braces 91. At the front ends are is illustrated in Fig. 1.

closed position,

have theirends bent aside as indicated by the reference numeral 101. Theedges of the drum '94 adjacent to the opening are rolled* over, as indicated b the reference numeral 99,-and the free e ge of the cover a 97 "is similarly rolled 'over as indicated by thezrefei'ence' numeral 100. Attached to the inside faoe-ofthe cover 97 is the longitudina'lly corrugated sheet' metal plate 102. The outside handles 103 each have one end 105 firmly, attached to the cover 97, but the other end 104 passes loosely through a hole in the cover 97;

Atthe rear ends of the top side braces 46 and '47 the studs 106 project inwardly. The sheet metal cover 110 has its rear edge rolled around these studs 106, as indicated by the reference numeral 107 thus the studs 106 form pivotal supports for the cover 110. Lugs 108 and 109 1 project "inwardly" from the braces 46 and 47 and form supports for the lateral edges of the hinged cover 110. Its free edge 111 is rolledover as shown in Figs. 1 and 2, and when the'covers are in There is a series of holes 112 alongthe'cover 110 and there is a space 113 between the rear edge of the cover 110 and the rearwa'll 41 of the washing machine tank.

Within the drum 94 of the washing machine are two longitudinal bafiles 114 supported at 'their ends by the end plates 115 and havin their edges rolled over as at 116. These ba es 114 are both disposed on one sideof the axis of .the drum 94. The concave wall of the drum 94 has numerous perforations 117.

The nature of the joint between the walls 41 and 43 of the washing machine tank is indicated by the "reference numeral 118 in Fig. 9.

p A drainage outlet 119 is tank, as shown in Fig. 2. t Assuming that the washing machine has the top covers all closed,'as shown in Fig. '2, and that it is'desired to open it up, the top cover 89 maybe rotated up about its front edge as an axis. Thus when the cover 89, has reached a substantially vertical position, itwill'slide 'down inside the f1-ont wall40 'of'the washing machine tank having its lateral edges "guided by the flanges; 34 on the corner braces 32; finally, the front edge' 90 of the cover will rest on the lower ends 36 of the flanges 34; the cover 89 will then be in the position shown provided for the The drum 94 has a reversely curved flexi-' thev the edge 90 of the cover 89' overlaps the'edgell'l ofthe cover 110.

1; Thereafter dmlmi'gt twin rotated on itstrunnions 71and- 67 untilthe opening in the top thereof*'takes the-positlQll" shown in dotted lines in Fig. 1. Then (referring to Fig; 2) adownwardpressure on'the' handles 103 will push the ends' 104' down," thus increasing the fiexureof the cover 97and' thereby ithdrawing the edge 100 of the cover 97 from 'under the'edge'99 of the drum94. --'='Thereafter the will'be rotatedabout the axis until it as sunies' the Fig. 1, the passed through the gaps 92-carried by the "cover plate 89.

Numerous advantages are secured bythis' arrangement of the be mentioned 'thefollowi'ngz In all posi tions, whether opened or closed, the'cover plate 89 is above the washing machine tank and when the cover'is opened-back and dropped 'down into the position'shown in Fig. 1', it is still within the tank so that all dripping of water from the tank to the floor is avoided. In removing clothing from t'he drum 94 through-the opening thereinjit is desirable that the 'dru'm should be held against rotation on its trunnions71-and 67.

cover '97- positionshown in dotted lines in" ends of the rolled edge being 93 into the -sockets' parts, among which may This is effectively accomplished by locking 4 the 'edgeof the hingedidrum cover 97" into the sockets 92. Occasionally it "may be found desirable to rub certain articles -of clothing ;n1ore or less when removing 9 them from the washing machine drum 94. The

corrugated sheet 102 is provided for this spection ofFig. 1, it is held in a convenient position and is immovably supported.

It willbe seen" that when the parts are in the position shown in Fig. 1, the clothing may be" readily passed through 'the'wringer 6121s it is lifted out from the dr'u'in'94. The drip from; the wringe'r will fall down" upon purpose, and as will be seen from-an in-' the auxiliary'jcover 1-10 "and will pass down I through the" holes 112 thereof and through the space'113 at the rear edge. VVhen itqi's desired to' liftthe" drum 94out from the tank, the wri'ngerel must first be removed by loosening-the thumb screw 64; then the hinged cover can-be thro'wnback against the rear edge 54 ofthe 'tanl'r and-the drum 94 can be lifted out, the=trunnions 71 and 67 passing up through the'openings 86in the flanges'85."

I I havefound that the disposition ofthe baflies 114 in the drum 94' is especially ad vant'ageous in thoroughly cleansing the clothes. i I i .The arrangement of the gears'tuds 81 on thee'nd of the drum, as shown'inFig." 1',- is

knownin"the*-prior 'artiand isnot here claimed? The driving pinion 80 is" shown in Fig. 1 in engagement with the studs 81 on the'inside thereof, but the oscillatory plate 75 permits the pinion 80 after having P so that 'ing machine.

- and 52 is stren 15, as g 32 and 30. As previously explained, the

as to afford time the clothes in a of the trunnions 71' having 41- new t :1:

turned the drum 94 through substantially one com lete revolution to shift to the outi Whenthe ear wheel .80 is on the inside, as

shown in Big. 1, its direction of rotation is a that when the suchjthat the drum is rotating in the direction'indicated by the arrow 120. At this the drumwill be carried u some distance on the center of avity of the. drum and its load willbe shifted farto the rear and. 67. Under some circumstances this might result in the force applied from the gear 80 to the studs 81 the efiect of lifting the trunnions out of their seats. But at such a time thejrod 83 asses above the trunnion 71 and positive y holds it down in its seat. It will be obvious from an inspection of Fi' lrthat when the gear 80 is on the outsi e of the circumferential series of studs 81, then the force will be apgied in the opposite.d-irection to these stu thus tending to hold the trunnions down in their seats; moreover, at this same time the rod 83- will be drawn to the right and its point will merely catch in one hole of the flange 7 0'. Thus, it will be seen that the rod 83 will not at such time prevent lifting the drum out of the tank. When the drum is put back in the tank, the studs 81 will engage the ear wheel 80-on the outside and this will have the effect to swing the plate aside so as to pull the'rod 83 back enough to admit the trunnion 71' to its seat. It will be see strong, simple and thatI have invented a durable all-metal wash- I desire to call articular attention to the manner in w 'ch the top frame comprisinglthe members 46-47-49:

gt ened by the corner posts well as by the inside corner braces side top braces 46 and 47 abut against the front and rear top braces 44 and 52. One purpose ofthis arrangement is to hold the rear brace 5.2 rigidly against strains on the wringer 61. The to];l braces have an angular cross section w ich greatly increases their stren h.---A s shown 1n the drawings, they are 0 greater depth at the corners. so screw threaded sockets for the screws orv stud bolts which' pass through from the corner posts 15. One purpose of posts. D

The auxiliary cover 110 prevents the rapid the rear wall thereof,

the corners of t fl :ang as yet, as laincd, it pets drip water from the wrmger 61 w drain down into the tank. I

The corner braces 32. and 30 not cnl to stiffen the frameviorkof the m' e, but they have screw passing through the, cornerposts are mtm duced. a

An inspection of Figs. 1 and 2 will show v washing drum reverses the direction of its rotation the door o ening the side thereof will be in front 0 the, ax sof the drum, that is, it will be directly at the left as viewed in Fig. 1, or directly at the right as viewed in Eig. 2. Thus it will be seen that at this time the two baflies 114: in the drum will be in the upper p is, they will be substantia ly above a horizontal plane containing the axis of the drum.
